Castor Oil vs. Lash Serum for Lash Health

When you’re looking for beauty tips for your lashes, brows, and skin, it makes sense to explore all your options. And if you do a little digging on how to get the best hair, lashes, and skin, there’s a natural remedy you’ll likely come across—and that’s castor oil.

Castor oil has become popular as a natural choice for cosmetics. Many devotees say it can improve hair, treat split ends, and add hydration to the skin.

But does it? The truth is, there can be a pretty significant gap between what people claim about castor oil and what it really does. This is especially true when we compare it to other beauty products.


So what, exactly, is the deal with castor oil? Does it work—especially when you compare castor oil vs. lash serum? And if you want to have the best lashes, brows, hair, and skin, what products do you actually need to get the results you want?

What is castor oil—and does it work?

First things first: what actually is castor oil?

Castor oil is a natural oil extracted from the seeds of the castor plant. That plant has deep roots in the beauty world. People have used castor oil for thousands of years, dating all the way back to ancient Egypt.

Castor oil has a thick, viscous texture. It is also high in fatty acids, especially ricinoleic acid. These fatty acids are natural humectants that help moisturize the skin and stop it from losing water.

People use castor oil in their beauty routines in many ways. They also tout various benefits of castor oil, such as:

  • Eyelash and eyebrow health. Castor oil has long been thought of as one of the more effective natural lash health solutions—and more specifically, for hydrating and nourishing the lashes. Some people claim that applying castor oil to eyelashes gives them a lusher, healthier look and can help strengthen the lashes.
  • Hair and scalp treatments. Castor is also used as a scalp and hair treatment. Some people massage the oil into their scalp to help with thinning hair. The basis of using castor oil for scalp health is the idea that the fatty acids in the oil can hydrate the skin, stimulate circulation, and promote stronger hair.
  • Moisturizing dry skin. Castor oil’s thick, hydrating properties have made it a go-to treatment for dry, flaky skin. Many apply castor oil to the scalp, face, and body to lock in moisture and soothe irritation. Because it’s a single ingredient product, it’s also often a go-to for people with sensitive skin conditions or other medical conditions.
  • Soothing split ends. As mentioned, many believe that castor oil can support stronger hair—and, as such, some people use it as a natural hair treatment to deal with damage, mend split ends, and protect from further breakage.
  • Condition lips. While lip balm is the typical choice for people with dry, cracked lips, some go for a more natural approach—and use castor oil as a natural lip conditioner.

However, while castor oil is often hailed as a do-it-all solution for lashes, brows, and skin—particularly by people who prefer a more natural approach to beauty—there isn’t a ton of evidence to back up that claim.

Research on castor oil

Castor oil certainly adds hydration to skin and hair (including the lashes and brows)—which is a great thing! But when it comes to results, that’s about it. There isn’t really any scientific evidence to back up claims that it can, for example, help hair look fuller or lashes look more lush; the benefits of castor oil for lashes stop at hydration. So, for people that are looking for more multifaceted results, chances are, they’ll find castor oil disappointing.

Not only is there limited evidence to back up claims around castor oil’s benefits, but using castor oil as a hydrator can actually cause issues—particularly with your skin. For some people, the thick, oily consistency can clog pores, leading to irritation and breakouts. (This can be especially true when applying castor oil near more sensitive areas, like the eyes).

Bottom line? Castor oil isn’t a magical cure all for better, hair health, lashes, brows, and skin, but it can provide moisturizing benefits.

Castor oil vs. lashes serum: How are they different?

Now that you know what castor oil does (and doesn’t do), let’s jump into why, when evaluating lash care options, you should incorporate a lash serum into your routine—as well as what lash serum you should try.

The biggest draw of eyelash serums is that they offer multiple benefits. Do they hydrate? Yes. But they do so much more than that. With the right lash serum, you can get antioxidants, hydrators, anti-aging peptides, and nutrients that help lashes thrive.

And when you compare that to castor oil, which offers a single ingredient—and a single benefit—the choice becomes clear.

Think about it this way. What if all of your skin and beauty products only offered a single ingredient and single benefit? You would have to apply a dozen products twice a day (or even more!) to get all the same benefits you’d get from fleshing out your routine with a few powerful, multitasking products.

So, when it comes to choosing a lash treatment, you’re always going to get more bang for your buck with a lash serum.
